It's hard to know how many of which size isn't it?
Nicky was 7lb 2oz, which took us completely by surprise since his brothers were 8lb 8oz and 8lb 13oz. Size 0 nippa bimbles were my favourite newborn nappy on him. They fit so well and I dyed all mine funky colours. They fitted him until he was about 10 weeks.
Zac didn't fit Newborn nappies at all and went straight into size 1.
